The SF600 SFX power supply from Corsair is a great unit, but one of the complaints I had in my review was that the stock ribbon cables were stiff and unwieldy in a tight SFF build. They weren’t terrible by any means, but they were a far cry from the very flexible cables SilverStone includes with their SFF units.
Today Corsair is addressing that with a Premium PSU Cable Kit for the SF-Series, featuring individually sleeved cables. While Corsair offers similarly sleeved cable kits for their other PSUs, this kit comes in lengths appropriate for a SFX power supply:
- 1x 24-pin motherboard: 300mm
- 1x 8-pin CPU: 400mm
- 2x PCIe 6+2: 400mm
- 1x SATA: 100mm / 115mm / 115mm / 115mm
- 1x 4-pin Molex: 100mm / 115mm / 115mm / 115mm
The first number is from the PSU-side to the first connector, and the second number is from the first connector to the second, and so forth.
These still use the Type-4 pinout though, so they could be used with any of the ATX power supplies that Corsair offers with the same pinout.
While I’m very glad to see Corsair offering their individually sleeved cables in SFF-appropriate lengths, I’m a bit miffed that they’ll be an additional cost on top of the power supply when better cables should have been included from the start. Maybe I’m being overly critical of the stock cables, because other reviewers and users have said it doesn’t bother them, but as someone who’s done very tight builds were every millimeter counts, I find the stock cables on the SF450/SF600 unbearable. This is a step in the right direction though and if it’s true that the squeaky wheel gets the grease, maybe the next iterations in the SF-series will come with more pliable cables by default.

Edit: Drew reports that these cables still felt pretty stiff but the paracord sleeving was nice to the touch and Corsair does not plan to bundle these with their PSUs anytime soon.
And not specifically related to the cables, but the SF450 and SF600 will be revised at some point to make the semi-fanless functionality more robust by setting the fan to turn on at a certain load level. On my SF600 I noticed sometimes the fan will kick on at idle after the machine has been running for a bit but it’s at a low RPM so I haven’t really complained about it. It is a problem though, however minor, so I’m glad to see Corsair addressing it.
Correction: Jon actually said that using a more sophisticated fan controller is something he wished they had done in hindsight and may do in a future revision, but there are no current plans for it.

The SF-Series cable kit launches today according to Mr. JonnyGuru himself (Jon Gerow) but no word on pricing yet.
